Gamo has entered the field of gas pistons with a Whisper! The Bone Collector Bull Whisper IGT air rifle is not only incredibly powerful, but it has many special features that'll set it apart from ordinary breakbarrel rifles with regular metal springs. Their proprietary gas piston means you can cock the gun and wait to take your next shot without worrying about a metal spring taking a set or weakening. Gas pistons are robust and do not lose anything in either area. Plus, gas pistons are known to shoot MUCH smoother and deliver less twang and vibration to the shooter!

Let's talk about the Shock Wave Absorber recoil pad. There's an entire industry centered around making aftermarket recoil pads. Their intent is to reduce the felt recoil, because constant recoil pounding into your shoulder is painful and will stop you from shooting as much as you want. While the gas piston is going to seriously reduce the vibration, the SWA recoil pad will stop you from feeling most of the recoil from the remaining movement of the gun.

In the past, Gamo customers have swapped out their triggers with aftermarket ones. No need to do that anymore! The Smooth Action Trigger is light years better than the previous version. It's smooth and predictable. What will that do for you? It'll improve your groups. Unpredictable and heavy triggers or triggers that don't break crisply are often responsible for delivering larger groups. You'll be amazed at how good a shot you are when you shoot the Bone Collector Bull Whisper IGT air rifle!

Things I liked:Weight,accuracy, stockThings I would have changed:Better scope definitelyWhat others should know:I killed a rabbit at 30 yards ,
Very accurate. I mounted the scope and the first shot was dead on.First time ever that has happened

Things I liked:The rifle. Smooth and solid. But you nearly need to be a gunsmith to create your own scoping/mounting system.Things I would have changed:The scope and mounts which are included. Gamo should just sell the rifle - and leave it to us to outfit w/ our own after-market mounts/sights pkg.What others should know:Will never hold a scope w/ dovetail mounts/rings. Gotta use a 4-screw Picatinny/Weaver base, then 4-screw ring caps. Will write a review on using a 2-screw picatinny base w/ a small stop pin that ate thru the soft metal rifle stop-pin hole (in a thousand shots).

Failure (after about 2K shots). Pity. It looked and felt so nice at the start. Bottom line: It won't hold a scope. And finally, the Picatinny/Weaver base (2 of them actually) ate their way back in the receiver Stop-Pin hole, and then bent the pins over. And these were husky 4-hex attaches. Only other thing I could have tried is to wire-weld the base to the receiver - just kidding, of course. Could write a book on this journey - to my Bone Yard of ruined parts.

Things I liked:Not muchThings I would have changed:Include a better scope and better rings or leave out the scope.What others should know:Had the rifle about two weeks and it started to fall apart. Accuaracy was never better then 2" @ 25 yards with any pellets Even tried a better scopedidn't help. Returned it for a refund.

You were smart - in immediately returning. I fought this degrading travesty of a rifle (and scope pkg) past the warranty period. It became a matter of principle - an obsession, really. I'll write a fresh review to warn other tender souls considering a purchase. Also, to warn other current users that their "fixes" will end in total failure. If the Bone at least had fixed sights, I would put it in the barn for point-blank shots at rats. Incidentally, I have 4 other Springers to compare to.

What kind of scope would you recommend for this rifle, and I was planning on buying the Gamo Red Fire Pellets for this gun, do you think they will perform well?

micheal from USA:

if you just want a scope i recommend the scope that came with your gun. if you want a good but cheap mil dot scope. i would go for the 4 x 32 hunter scope made by leapers. now about the pellet, i'm not sure how well it will do. but the best pellets i used: gamo hunter, and the crosmen premier. other then that have a good time shooting.
ps. the scope rings that come with your gun is 3/8 dove. when you buy a scope. make sure that you check what kind of scope rings or mount it comes with.
pps. i have a: Leapers Accushot 1-Pc Mount w/1" Rings, High, 11mm Dovetail. and it work like a charm.
